AIR-WASHING DEVICE.

To all whom it may concern Be it known that I, CHARLES L. WORRALL,

. a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new anduseful Improvements in Air-Washing Dievices, of which the following is a specification.

This invention relates to air purifying devices and has for its object the provision of a device adapted for use particularly upon .a tractor whereby air may. be washed prior to its entry into the air inlet of the carbureter of the tractor motor, the advantage being that the device will remove from the air dust or other gritty matter which might and in fact would injure the motor and clog the carbureter. 5

An important object is the provlsion of a device of this character so constructed that the air will have the surplus moisture reinoved therefrom subsequent to this washing and prior to its admittance to the carbureter.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture and installation, highly efiicient in use, durable in service, and a general improvement in the rt, v With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illusthe line 5-5. of Fig. 2.

Referring more particularly a; thedrawings, the letter A'designates, rather diagrammatically, a tractor,-B designates the carbureter thereof, and C designates the air 1n- 7 take of the carbureter.

In carryin out my invention 1 provide a tank 10 whic is formed of sheet metal and which is preferably rectangular and oblong.

Specification of Letters i'atent.

. rectangular casing 15 includin rateiitea May is, rear;

Application filed June 11, 1920. Serial No. 888,260.

This tank is provided adjacent the top of one end wall w th an air inlet opening 11 and is provided in Us top adjacent the'other end with an air outlet opening 12 connected with the air inlet C of the carbureter by a hose or pipe 13. This tank is provided with a flanged removable cover 14 which ma be secured by any desired means. ter should be introduced within the'tank to any desired level, preferably abouttwo-thirds of the way up, as shown by the line D. The tank is further provided at the desired water ,line with a cock ldwhereby excess water' may bedrained 'ofi' to obtain the desired level. At some desired point in its bottom. the tank is also provided with a drain plu 17 whereby the water may be drained 0 when dirty.

Disposed within the tank is an inverted and a top fromwhich depen s a vertical plate 18 which extends downwardly to a point somewhat below the water level so that air drawn through the tank will have to pass through the water. At a point spaced from the plate 18 I provide a vertical sides, ends plate 19 which terminates short of the top i and which has its upper edge formed with a flange 20 extending toward the plate 18. Secured to the plate 19and to the sides of the casing and also to the opposite end is a horizontal plate 21 which is disposed slightly above the water level and from the nnder side of which extend verticalplates 22 which extend to the bottom and which are for the purposeof preventing undue slopping of the water back and forth within the tank when the tractor travels over rough" ground. The plate 19 and also the plates 22 are provided at their lower edges with open-, ings 23,.which permit passage of the water through all the plates. Disposed above the plate 21' is a-sle'cond horizontal plate 24 which extends entirely to one end of the v casing and which hasits other end extending vertically upwardly to provide a vertical plate 25 spaced from the plate'19 and terminating in the same horizontal plane therewith. A. similar third horizontal plate 26 is provided arranged above the plate 24 and having one end extending vertically upwardly, as shown at 27 in spaced relation to the plate 25 and extending to the same height. The plates 21, 24and 26 are perfo are arranged, respectively, between the plates 19 and 25 and between the plates 25 and 27 and I also provide a downwardly extending plate 30 adj aeent the outlet 12. At

the lower edges of the plates 28, 29 and 30 are flanges 31 which serve as gutters and which are inclined toward one side of the casing and provided with holes 32;

In the operation of the device it will be seen that air sucked into the carbureter must pass through the 'tank and must pass throu h the water therein below the plate lifter the air bubbles up throu h the water it will pass over the horizonta plate 20 and then in a circuitous course around the plates- 28, 25, 29, 27 and 30 before it reachesthe outlet 12. As the air passes along this circuitous course and strikes the various bafile plates any spray'or drops of moisture will adhere to the vertical plates so that when the air reaches the outlet it will contain no surplus moisture. The

water thus condensed on the vertical plates.

28, 29 and 30 will drop therefrom into the troughs 31' and be led thereby to the sides of the casing and onto the horizontal plates 21, 24 and 25 and as these are. perforated the water will pass back into the main body at'the bottom of the tank.

From the foregoing description and a study of the drawings it will be apparent that I have thus provlded avery simple and inexpensive device by means of which air may be washed and all dust and grit removed therefrom so that the air willbe in proper condition for mixture with'the gasolene vapor used in running the engine. It will also be observed that undue splashing or slopping of the water within the tank will be prevented and that the device will be consequently very eflicient in use I While I have shown and described the preferred embodiment of my invention, it is X will not depart from the s irit of the invention or the scope of the su joined claims.

plates'within the tank, vertical plates at the ends of said horizontal plates toward the inlet end of the tank terminating in spaced relation to the top of the tank, and a plurallty of plates depending from the top of the casing between said vvertical plates.

2. A device of the character described comprising a tank-provided in one'end with an an inlet and at its other end with an air outlet, said tank containing water, a vertical plateextending downwardly below the water level at the air inlet end of the tank, a' plurality ofhorizontal plates within the tank arranged in spaced relation and perforated, all of said horizontal plates extending to the outlet end of the tank and being of successively decreasing lengths, vertical plates at the other ends of said horizontal plates terminating in spaced relation to the top of the tank, and a plurality of depending plates extending from the top of the cas- 'the tank, a plurality of spaced' erforated horizontal plates wlthin the tan vertical plates at the ends of said horizontal plates toward the inlet end of the tank terminatmg in spaced relation to the top of the tank,

and a plurality of plates depending from the top of the casing between said vertical lates, and out-turned. flanges formed at the ower edges of said last named plates and constituting troughs, said flanges having their. end portions provided with holes.

' In testimony whereof I aflix my signature.
